How do you get covered for health insurance in italy?

I want to know, Im an american
--------------------
We don't have insurance in Italy. There is the Azienda Sanitaria Nazionale (ASN), which pays everthing for us. If you need urgent assistance, you go to "pronto soccorso" in hospital and they must cure you, without asking you nothing. For everything else, everybody has a "medico di base": he's a family doctor, which examine you when you need, for free. Doctors are then paied by ASN (and we pay it with general taxes). There's a private sector, too. But you don't need insurance: you go and pay directly.
